Another segment losing service is the EB from Spokane to Seattle via Yakima, Ellensburg, and Auburn.
That happened when the North Coast Hiawatha went away. Originally for some reason the North Coast Hiawatha used to go via Stevens Pass, and the Empire Builder via Stampede Pass. When the NCH died, the EB was rerouted via Stevens Pass, and the new Portland section of the EB was created which was routed via the SP&S Columbia Gorge route thus allegedly maintaining service to Pasco, and serving a new route. Of course at that time the other bank of Columbia River was also served by the Pioneer, which later went away, leaving the EB Portland Section as the sole train serving Columbia Gorge.
I'm on Cape Cod at the moment and arrived on the MBTA Commuter Rail CapeFlyer. the last train to the Cape ended in the 1990s was Cape Codder that ran one round-trip per weekend (arriving on Friday, leaving Sunday) during summer only to Hyannis (via a different route on the mainland compared to today's CapeFlyer (its its first season)
Cape Codder ran only very briefly. It was a service started by Amtrak funded partly by Massachusetts AFAIR (and could be recalling wrongly), and it went away when the funding went away.
I just realized a few interesting things:
1. If the Hilltopper existed today it would not have required any state to fund it. Its meandering route stretched to over 1500 miles!
2. There was no rail service to Niagara Falls until after 1975. There was a motor coach connection from Buffalo.
3. There was no through service to Toronto (Maple Leaf). Going to Toronto involved a change to an RDC at Buffalo. The Rainbow Bridge was not used for the service.
4. There were only three daily and two weekdays only trains between Washington DC and Boston!
5. The number of trains between Albany and Buffalo has not changed substantially since 1975. It is time that NY State did something about that.
6. The New York - Buffalo - Detroit service via Canada changed name from Empire State Express to Niagara Rainbow sometime between 1972 and 1975. The connection to Toronto was also from this train.
7. On A Day there was no service west of Buffalo. Buffalo was a terminus for Amtrak service. Nor was there anything going north of Albany or Springfield! So no Adirondack or Montrealer! LSL started in the revised July 71 timetable.
8. On weekdays there were as many total number of trains running between New York and Washington DC as there are Acelas today, in the revised July 1971 timetable.
9. In 1971 July revised timetable, the North Coast Hiawatha ran as a section of the EB three days a week, running together as a single train from Chicago to Minneapolis and then again from Spokane to Seattle, and the whole trains traveled bya Stampede Pass. There was no passenger service through Stevens Pass, the current route of the Seattle section of the EB.
Fascinating stuff....
